Time has always perplexed the human race. We’ve tried to define it, track it, and measure it since the emergence of civilization. However, facts like these listed here show us how distorted our perception of time can be and how much we still need to learn about the fourth dimension.

1. Cleopatra lived closer to the building of Pizza Hut than the pyramids.

The Great Pyramid was built cerca 2560 BC, while Cleopatra lived around 30 BC. The first Pizza Hut opened in 1958, which is about 500 years closer.

Obama was seated next to a little girl on an airplane. He turned to her and said, “Let’s talk. I’ve heard that flights go quicker if you strike up a conversation with your fellow passenger.”

The little girl, who had just opened her book, closed it slowly and said to Obama, “What would you like to talk about?”

“Oh, I don’t know,” said Obama. “How about What Changes I Should Make To America?” and he smiles.

“OK,” she says. “That could be an interesting topic. But let me ask you a question first. A horse, a cow, and a deer all eat the same stuff – grass. Yet a deer excretes little pellets, while a cow turns out a flat patty, and a horse produces clumps of dried grass. Why do you suppose that is?”

Obama, visibly surprised by the little girl’s intelligence, thinks about it for a second and finally says, “Hmmm, I have no idea.”

To which the little girl replies, “Do you really feel qualified to change America when you don’t know shit?”

Prescription drugs are easy to get a hold of, whether they come from a doctor or not. The other week I bought three Valium from my flatmate. I used one to catch up on sleep and gave the others to a friend who likes to mix them with alcohol. She practically fell asleep standing up. It was only then that I thought about how I probably shouldn’t be buying prescription medication and doling it out. But because Valium is technically legal, and because I was four drinks down at a free bar when I gave them to her, it didn’t really register at the time.

Drugs like these–the painkiller tramadol, psychoactive benzodiazepines like Xanax and Valium, or anti-epilepsy drug Lyrica–make you feel like you’re floating on a cloud. In the UK, they come with lower penalties than illegal drugs if you’re caught buying or selling them, no penalties for possession, and are generally cheaper. This is their appeal and also their danger.
